Consider the following statements:1. Maize can be used for the production of starch.2. Oil extracted from maize can be a feedstock for biodiesel.3. Alcoholic beverages can be produced by using maize.Which of the statements given above is/are correct?

a1 only
b1 and 2 only
c2 and 3 only
d1, 2 and 3
✓ Correct answer: d) 1, 2 and 3
ExplanationStatement 1 is correct: Maize is a primary source for commercial starch production.Through a wet milling process, maize kernels are separated into components such as starch, oil, protein, and fiber.The extracted starch is utilized in multiple industries, including food, paper, and textiles.Statement 2 is correct: Maize oil, also known as corn oil, can be used as a raw material for biodiesel production.Through a chemical process called transesterification, the oil reacts with short-chain alcohols such as methanol or ethanol, using a catalyst to produce biodiesel efficiently.Statement 3 is correct: Maize plays a significant role in the production of various alcoholic beverages.Its starch is broken down into sugars, which are subsequently fermented to produce alcohol.This process is crucial in crafting drinks like bourbon whiskey, which traditionally uses a mash containing at least 51% maize.183
